Describe the bug

OC throws InvalidOperationException after I upgrated OC from v1.8.4 to v2.1.2 in runtime

An unhandled exception occurred while processing the request.
InvalidOperationException: The model item passed into the ViewDataDictionary is of type 'OrchardCore.DisplayManagement.Zones.ZoneHolding', but this ViewDataDictionary instance requires a model item of type 'OrchardCore.Users.ViewModels.LoginViewModel'.
Microsoft.AspNetCore.Mvc.ViewFeatures.ViewDataDictionary..ctor(ViewDataDictionary source, object model, Type declaredModelType)

To Reproduce

1. Go to home page
2. Go to /admin
3. Throws InvalidOperationException

Do you have a login form-overriding template? Because that changed in 2.0, and you'll need to take the latest source as the baseline for the override: https://docs.orchardcore.net/en/latest/releases/2.0.0/#users-module

I am guessing you have a template overriding the login.cshtml which uses to accept LoginViewModel and now it accepts IShape instead.

Make sure your custom login.cshtml looks like this

OrchardCore/src/OrchardCore.Modules/OrchardCore.Users/Views/Account/Login.cshtml

Line 4 in d21acb2

@using OrchardCore.Settings

Hi @Piedone @MikeAlhayek ,
Good, I have a login form-overriding template. Thanks!
